Bedrock Automation released full integration of flow computer functionality into the OSA platform.

The new OSA +Flow family embeds Flow-Cal measurement applications into the Bedrock Automation platform. Flow-Cal’s software has long been the industry’s choice for flow measurement and production-accounting data.

“Flow computer users are at a critical juncture. The measurement and control technology they have been using are mostly at the end of life and many of the incumbent new offerings are built on technologies and ideas that are already out of date,” said Bedrock Automation Founder, Chief Executive, and CTO, Albert Rooyakkers. “We approach the application differently by integrating the … measurement software directly into the Bedrock OSA automation platform. With one automation platform and a single zero-cost engineering environment, users can configure measurement and custody transfer applications, program all field I/O and control strategies, and deploy industrial connectivity protocols such as HART, Ethernet IP, and Modbus alongside OPC UA and MQTT.”

The OSA +Flow software has been incorporated across all Bedrock controllers providing unlimited scalability for PLC, RTU or DCS flow control requirements at custody transfer stations, separators, and other oil and gas production facilities. These solutions include full support of multi-drop serial, Ethernet, and HART for Coriolis, ultrasonic, and smart transmitters.

The OSA +Flow family consists of two products: the OSA +Flow platform and OSA Remote +Flow. The OSA +Flow is installed in the standard Bedrock OSA pin-less backplane with unlimited scalability for PLC, RTU or DCS flow control at custody transfer stations, separators, and other oil and gas facilities. The OSA Remote +Flow is designed for applications requiring only 10 or 20 hard I/O, such as most custody transfer stations.
